Cya

Soundcloud
One can't just start talking about Cya's music without a mention about his Soundcloud. I won't be listing his songs there since they're already fairly well organised and credited there. ^^ https://soundcloud.com/latecya 

For translations, studioweus (♡) has lyrics videos, of which you can find a masterlist here: https://weusarchives.tumblr.com/latecya 

- Promise
This is an OST for the web drama The Miracle, by DongHyun of Boyfriend, and in which he featured. He does not appear in the MV though!
He's credited in 4th place as lyrics-writer, so he most likely wrote his own rap.
Released on 2016.12.12

- Crazy & Crazy ( ㅁㅊㄷㅁㅊㅇ )
This self-produced song was included in Oneus' "Light us" album, released on 2019.01.09. He also features in it!

Lyrics by: Ravn, Leedo, Cya
Arranged by: Cya, JDW

There's also a band version!
